CLEANING AND MAINTENANCE

CARE OF GUIDE BAR

Uneven bar wear causes most guide bar prob-

lems. Incorrect sharpening of chain cutter

and depth gauge settings often cause this.

When bar wears unevenly, it widens guide

bar groove (see Figure 30). This causes chain

clatter and rivet popping. Saw will not cut

straight. Replace guide bar if this occurs.

Inspect guide bar before sharpening chain.

A worn or damaged guide bar is unsafe. A

worn or damaged guide bar will damage

chain. It will also make cutting harder.

CLEANING SAW BODY

NOTICE: Below are instructions

for servicing your chain saw. Any

servicing not mentioned below

should be done by an authorized

service center.

WARNING: Remove battery

from chain saw before servicing.

Severe injury or death could oc-

cur from body contact with mov-

ing chain.

WARNING: Cutting edges on

chain are sharp. Use protective

gloves when handling chain.

WARNING: When cleaning saw

body,

• do not submerge saw in

any liquids

• do not use products

that contain ammonia,

chlorine, or abrasives

• do not use chlorinated

cleaning solvents, carbon

tetrachloride, kerosene,

or gasoline

Keep saw body clean. Use a soft cloth damp-

ened with a mild soap and water mixture.

Wipe saw body to clean.

Normal Guide Bar Maintenance

1. Remove guide bar from chain saw.

2. Remove sawdust from guide bar

groove periodically. Use putty knife

or wire (see Figure 31).

3. Clean oil slots after each day of use.

4. Remove burrs from sides of guide

bar. Use ﬂ at ﬁ le to make side edges

square.

Replace guide bar when

• bar is bent or cracked

• inside groove of bar is badly worn

4. Hold ﬁ le guide level. Make sure 30°

mark on ﬁ le guide is parallel to cen-

ter of guide bar (see Figure 33). This

will insure that you ﬁ le cutters at 30°

angle.

5. File from inside towards outside of

cutter until sharp. Only ﬁ le in this one

direction (see Figure 33). Note: Two or

three strokes with ﬁ le should sharpen

cutter.

6. After each cutter is sharpened, move

chain forward to sharpen next cutter.

File all cutters on one side of chain.

7. Move to other side of chain and repeat

process.

WARNING: Remove battery

from chain saw before servicing.

Severe injury or death could oc-

cur from body contact with mov-

ing chain.

WARNING: Cutting edges on

chain are sharp. Use protective

gloves when handling chain.

SHARPENING SAW CHAIN

Keep chain sharp. Your saw will cut faster

and more safely. A dull chain will cause

undue sprocket, guide bar, chain, and motor

wear. If you must force chain into wood and

cutting creates only sawdust with few large

chips, chain is dull.

Items Needed to Sharpen Chain

Purchase these items from your local

dealer, hardware store, or chain saw sup-

plies outlet.

• 5/32" round ﬁ le

• Depth gauge tool

• File guide

• Vise

• Medium sized ﬂat ﬁ le
